ER1804 – TBus® Four Port Receiver

NV-ER-1804
Overview

[NV-ER1804]

The NVT Model NV-ER1804 TBus Ethernet over Coax/UTP Receiver is a compact bus-architected receiver hub that has four TBus ports, each capable of supporting multiple TBus transmitters and their subsequent 10/100BaseT Ethernet and PoE+ powered devices.

The TBus transmission medium can be coax, 2-Wire/UTP, or Shielded twisted-Pair. Data rates up to 150 Mbps are achievable, making these devices the ideal choice in new or legacy installations where existing cable is re-deployed as part of an upgrade to IP cameras. 56 VDC is provided by a local power supply. These transmitters are extremely simple to use, with no IP or MAC addressing required. Status LEDs indicate power and link connectivity/quality/activity for RJ45 and TBus ports.

The NV-ER1804 is backed by NVT Phybridge’s award winning customer support, limited lifetime warranty, and advance replacement.

*Distance and number of devices supported may lower due to limited power supply capacity and wire voltage-drop, or data-rate limiting due to the selected wire’s high-frequency signal attenuation.

Tech Specs
  • Transmit 10/100 BaseT Ethernet up to 8,000ft over RG-59/U, 2,000ft over 2-Wire/UTP, or 1,300ft over Shielded Twisted Pair*
  • The TBus architecture allows multipoint operation in any star or daisy-chained topology, with any combination of wire types and up to 16 remote transmitters/IP cameras
  • Transparently supports all networking protocols (UDP, TCP/IP, HTTP, Multicast, etc.)using advanced 128-bit AES encryption
  • 10/100/1000 uplink Ethernet connectivity
  • Easy configuration, no PC required
  • 56 VDC is distributed over the Tbus to all connected equipment. PoE, PoE+, or High Power PoE cameras (or other PoE devices), up to 50 Watts* are supported
  • Built-in transient protection; Industrial temperature range

*Distance and number of devices supported may lower due to limited power supply capacity and wire voltage-drop, or data-rate limiting due to the selected wire’s high-frequency signal attenuation.

Accessories
NV-BNCA

View Datasheet

The NVT Model NV-BNCA is an adaptor used by NVT’s IP transceivers to convert from BNC to 2-wire. It ships standard with the NV-EC1701U transceivers, but can be used with TBus products as well. The NV-BNCA may be used mid-span along a wire run whenever conversion between coax and 2-wire cable is required.
